The Clearly Seen Ones

I wouldn't want this blog to become a mere conduit for interesting facts derived from wikipedia. But, having said that ...

The English word "dragon" derives from Greek δράκων (drákōn), "dragon, serpent of huge size, water-snake", which probably comes from the verb δρακεῖν (drakeîn) "to see clearly".

What's nice about this is the ironic etymology in naming an imaginary, and therefore (strictly) invisible, beast 'the clearly seen one.' But it's right, isn't it? Dragons are clearly seen, in cultural imaginarium at any rate.
